Study Notes

Vertebral Column Overview

The vertebral column consists of different segments: cervical, thoracic, lumbar, sacrum, and coccyx.
Cervical vertebrae are the topmost vertebrae, typically consisting of seven vertebrae (C1-C7).
Thoracic vertebrae are located in the mid-back, usually numbering twelve (T1-T12).
Lumbar vertebrae comprise the lower back and consist of five vertebrae (L1-L5).
The sacrum is a triangular bone made up of five fused vertebrae, forming the back of the pelvis.
The coccyx, or tailbone, forms the terminal end of the vertebral column and is composed of three to five fused vertebrae.

Key Vertebral Components

Transverse Process: Projections on either side of a vertebra that provide attachment for muscles and ligaments.
Spinous Process: The bony projection off the back of a vertebra, serving as an attachment point for muscles.
Intervertebral Foramen: Openings between vertebrae that allow spinal nerves to exit the spinal column.
Intervertebral Disc: Fibrocartilaginous cushions between vertebrae that act as shock absorbers.
Pedicle: The bony part of a vertebra that connects the body to the vertebral arch.

Verterbral Structure

Body of Vertebra: The anterior portion that bears weight.
Vertebral Foramen: The central hole in each vertebra through which the spinal cord passes.
Vertebral Arch: The arch formed by the pedicle and lamina, surrounding the vertebral foramen.

Regional Differences in Vertebrae

Body of Axis: Refers to the Dens which connects with the atlas allowing head rotation.
Transverse Foramen: Unique openings found in cervical vertebrae allowing passage of vertebral arteries.
Superior/Inferior Articular Processes: Projections that help vertebrae connect with adjacent vertebrae and facilitate movement.

Rib Components

Facet for Rib: The location on thoracic vertebrae where ribs articulate.
True Ribs: The first seven pairs of ribs directly connect to the sternum.
False Ribs: Ribs eight through ten that connect to the sternum indirectly via cartilage.
Floating Ribs: The last two pairs of ribs that do not connect to the sternum.

Sternum Components

Manubrium: The upper segment of the sternum.
Body of Sternum: The central part of the sternum, where most ribs attach.
Xiphoid Process: The cartilage tip at the lower end of the sternum.
Sternal Angle: The joint between the manubrium and body of the sternum, indicating the level of the second rib.

Pelvic Anatomy

Coxal Bone: Also known as the hip bone; consist of ilium, ischium, and pubis.
Acetabulum: The socket of the hip joint where the thigh bone meets the pelvis.
Pelvic Brim: The edge of the pelvic inlet, which separates the true pelvis from the false pelvis.
Pubic Symphysis: The joint where the left and right pubic bones meet.

Sex Differences in Pelvis

Male Pelvis: Generally narrower with a more heart-shaped pelvic inlet.
Female Pelvis: Wider with a rounder pelvic inlet, adapted for childbirth.

Curvature of the Spinal Column

Concave Curvature - Cervical: Inward curvature of the cervical spine.
Convex Curvature - Thoracic: Outward curvature of the thoracic spine.
